Troubleshoong Resources Overview
To troubleshoot a QFX5200, you use the Junos OS CLI, alarms, and LEDs on the network ports,
management panel, and components.
• LEDs—When the Roung Engine detects an alarm condion, it lights the red or yellow alarm LED on
the management panel as appropriate. In addion, you can also use component LEDs and network
port LEDs to troubleshoot the QFX5200. For more informaon, see the following topics:
• "QFX5200 Chassis Status LEDs" on page 24
• "QFX5200 Management Panel Overview" on page 18
• "QFX5200-32C and QFX5200-32C-L Port Panel" on page 9
• "QFX5200-48Y Port Panel" on page 13
• "QFX5200-32C and QFX5200-32C-L Fan Module LED" on page 37
• "QFX5200 AC Power Supply LEDs" on page 45
• "QFX5200 DC Power Supply LEDs" on page 52
• CLI—The CLI is the primary tool for controlling and troubleshoong hardware, Junos OS, roung
protocols, and network connecvity. CLI commands display informaon from roung tables,
informaon specic to roung protocols, and informaon about network connecvity derived from
the ping and traceroute ulies. For informaon about using the CLI to troubleshoot Junos OS, see
the appropriate Junos OS conguraon guide.
• JTAC—If you need assistance during troubleshoong, you can contact the Juniper Networks
Technical Assistance Center (JTAC) by using the Web or by telephone. If you encounter soware
problems, or problems with hardware components not discussed here, contact JTAC.
